ROAD-DRAG.

Application filed January 23, 1912.

T (ZZZ 70710121 it may concern Be it known that we, Jon's II. CHERRY and Lotus it. hljnmmnr, citizens of the United States of America, and residents c'l vl aterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in HoadDrags, of which the following is a specification.

Our invention relates to improvements in road drags, and the object of our improvement is to provide a road drag which is composed of a pair of spaced apart bars or blades, with convenient and suitable means fiior pivotally connecting them together, and for securing them in such an adjusted position indcpendently, as to permit of either being adjusted to receive either a vertical position or an inclination to the front or rear. This object we have accomplished by the means which are hereinafter described and claimed. and which are illustrated in. the accompanying drawings, in which:

Figure 1 is a perspective view of our improved road drag, with a portion of the seat-sup 'iorting beam broken away. Fig. 2 is an enlarged transverse section o'l' said road drag, taken on the line (L-Z) of Fig. 1. looking in the direction of the arrow, and having parts broken away. Fig. 3 is a detail view of a portion of the rear side of the rear blade, showing the pivotal connections therewith and with the intermediate pair of uprights to the middle transverse bar and the rear link to one of the hand levers.

Similar numerals of reference denote corresponding parts tl'iroughout the several views.

The drag comprises a pair of spaced apart rectangular blades 1 and 2 of like size and :lorm, though the dimensions and form may be varied if desired. Since the stresses upon the blades due to the irregular conformation ot the surface traveled over by them will tend to bend or buckle them, we have provided on the rear face of each blade an angle-bar reinforcement, shown at S and 9, which are riveted to the blades and render them sufliciently stiff. The blades are pivotally connected together by means of transverse bars 3 and 5 near each end. and an intermediate bar 4-, said bars ordinarily lying in a horizontal plane and par allel with each other. These bars are piv- Specification of Letters Patent.

otally connected to the upper part of: the blades by the :l'ollowing means. As shown best in Fig. 3, pairs oli uprights l0 and 11, formed of angle-bars, are riveted in a spaced apart relation to the rear faces of said blades 1 and 2, there being a pair near each end 0 li each blade and an intermediatcly located pair at the middle o't each blade. twaid transverse bars are pivoted to said blades by means oi. the pintle-bolts 27 and 111 respectively, at a location above the upper edge of each blade, since the uprights project upwardly above the blades. Said bars may be connected by means oi a rod 7 and a beam or plank 19, and a seat may be supported on the latter. in order to adjust the inclinations of the said blades 1 and 2 independently of each other. and then hold them in an adjusted position. we have adopted the following means: The numerals ll and 1:") denote lmnd-levers. both being fulcrumed on a pivot-pintle 29 at a distance above their lower ends to the middle bar i, and adapted to move past [he raclcsegments '18 and 19 respectively also sup ported by said bar l. llach hand lever has a dctent 17 adapted to be projected removably into either of the notches on its adjacent rack-segment, by means ot a spring .16 mounted on the lever and connected in a well-known manner to a link "30 and pivoted linger-piece 91, or I'QtliOCtilVQl), whereby the deteuts may be operated indepemlently of each other. A link (3 has its rear end passed through a slot in the rear blade 1 and pivoted on a pintle-bolt era to the lower parts of the members 10-11 of the middle pair of uprights. The forward end of said link is pivoted to the lower end of the hand lever 14- on a pivot-pintlc Q8. .iinolher link 13 has its forward end pivoted on a pivot-pintle between the members 'l()-'l '1 of the middle pair of uprights secured to the rear "face oil. the :l'ront blade 2, while its rear end is pivoted to a 'iivobpintle iii on the lower end of the other hand lever 15.

A. dra'tt-mnnection 5.25 may be connected by swivels ii and 23 to the orwardly-projccting forward ends of the end transverse bars 3 and 5.

The hand levers are conveniently located within reach of the opcrator seated on the scat supported on the beam 12. and may be iiulepcndently operated as desired to either maintain the blades in a vertical position,

' or tilt either separately forwardly or rearwardly according to the nature of the surface to be passed over or acted upon and the results desired of either blade. Each blade is therefore permitted three adjustments independent of the other blade, and the drag is thus rendered competent for any variety of function within its scope.

Having described our invention, What we claim as new, and desire to secure by Letters Patent, is:

A road drag, comprising front and rear blades, spaced apart, transverse bars pivotally connected to said blades, abutting opnected between the lower end of one hand lever and a part of the front blade below the pivotal connection of said transverse bars to said blade, a link pivotally connected to the lower end of the other hand lever and to a part of the rear blade below the pivotal connection of the said tranverse bars to said blade, and means for detachably securing independently either hand lever in an adjusted position.

Signed at Waterloo, Iowa, this 5th day of Jan. 1912.
